<h3>Basic Disk Images</h3>

<p>There are two ways in AppleWin to create a blank floppy disk image:</p>

<h4>A) Native Disk Menu</h4>

The easiest way to to create a blank disk image is to:

<ol>
  <li><strong>Right-Click</strong> on the Drive 1 <img src="img/tb-drv1.png" /> toolbar button (or press <span style="font-family: Courier New,Courier,monospace;">Ctrl-F3</span>) to open the drive pop-up menu.<br>

  <br><img src="img/disk_new_140kb_disk.png" style="width: 33%; height: auto;" border="1"/></li>

  <li>Depending on the <i>File System</i> desired select:

<p><ul>
      <li>For a blank ProDOS disk select: <strong>New ProDOS 5.25" (140KB) disk image (Standard 35 Track)</strong>, or</li>
      <li>For a blank DOS 3.3 disk select: <strong>New DOS 3.3 5.25" (140 KB) disk image (Standard 35 Track)</strong>.</li>
    </ul>
</p>

<p>Newer programs tend to use ProDOS while older programs tend to use DOS 3.3.</p></li>

<p><strong>NOTE:</strong> By default a new ProDOS disk image will have four files copied onto it:

<ul>
  <li><span style="font-family: Courier New,Courier,monospace;">BITSY.BOOT</span></li>
  <li><span style="font-family: Courier New,Courier,monospace;">QUIT.SYSTEM</span></li>
  <li><span style="font-family: Courier New,Courier,monospace;">BASIC.SYSTEM</span></li>
  <li><span style="font-family: Courier New,Courier,monospace;">PRODOS</span></li>
</ul>

<p>If you want to free up more room on a ProDOS disk you can toggle these individually on/off for which file(s) should be copied. (Your preferences persist for the next time you use AppleWin in the registry.)</p>

  <li>You will then be asked to optionally name the disk image.<br>

<p>The name will default to:</p>
<ul>
    <li><i>blank_floppy_###.po</i> for ProDOS, or </li>
    <li><i>blank_floppy_###.do</i> for DOS 3.3.</li>
</ul>

  <p><strong>NOTE:</strong> The ### is the current date-time-stamp in YEAR-MON-DAY-HHh-MMm-SSs format.</p></li>

  <li>Click <span style="font-family: Courier New,Courier,monospace;">SAVE</span> when ready.</li>
</ol>

<p>You are now ready to use your new disk image.

<h4>B) Classic Disk Creation</h4>

<p>In older versions of AppleWin there was only one way to natively create an empty disk image.
To create an empty disk image:</p>

<ol>
  <li>Clicking on the drive icon, and</li>
  <li>Type an image file name ending in <span style="font-family: Courier New,Courier,monospace;">.DSK</span> (or <span style="font-family: Courier New,Courier,monospace;">.DO</span>) which <i>doesn't</i> already exist.
</ol>

<p>AppleWin will automatically create a new 5.25" image
(standard 140 KB, 16 sectors/track, 35 tracks) file which is empty and <strong>non-bootable.</strong> (See <a href="ddi-sizes.html">Disk Sizes</a> or <a href="ddi-advanced.html">Advanced Formatting Options</a> for more information.)</p>

<h5>Manually putting DOS 3.3 on a blank disk so it is bootable</h5>

<i>Formatting</i> a disk will put a File System on it and (optionally) copy a Disk Operating System (DOS 3.3, ProDOS, etc.) onto it.  This will also make the disk <i>bootable</i> (copies a small assembly language program called the boot sector to Track 0, Sector 0) such that you can use <span style="font-family: Courier New,Courier,monospace;">PR#6</span> too boot it.</p>

Specifying a new disk image is like inserting a blank,
unformatted floppy disk into a real drive.&nbsp; This means that
the image must be formatted (either by the emulator or some other utility) before it can be used.
Specifically, this is what you would do using DOS 3.3:</p>

<ol>
<li>Click on the Drive 1 <img src="img/tb-drv1.png" /> toolbar button (or press <span style="font-family: Courier New,Courier,monospace;">F3</span>)</li>

  <li>Load a master DOS 3.3 disk image (eg. <i>DOS 3.3 System Master - 680-0210-A.dsk</i>) in drive 1 and boot the emulated Apple. </li>

  <li>Boot the emulated Apple by clicking on the <img src="img/tb-run.png" /> button (or press <span style="font-family: Courier New,Courier,monospace;">F2</span>). </li>

  <li>Click on the Drive 1 <img src="img/tb-drv1.png" /> toolbar button (or press <span style="font-family: Courier New,Courier,monospace;">F3</span>) again.</li>

  <li>Instead of selecting a disk image from the list, type in a name for a new disk image and press enter.<br>
  <p><b>NOTE:</b> The filename SHOULD end in <span style="font-family: Courier New,Courier,monospace;">.DSK</span> or <span style="font-family: Courier New,Courier,monospace;">.DO</span>.</p>
  </li>

  <li>Type in a program that you want DOS to run whenever this new disk is booted. A simple but useful
program is this Applesoft BASIC program:<br>

    <br>

    <span style="font-family: Courier New,Courier,monospace;">10 PRINT CHR$(4);"CATALOG"</span><font face="Courier New"><br>

    </font><br>

  </li>

  <li>Type <span style="font-family: Courier New,Courier,monospace;">"INIT
HELLO"</span> to initialize (format) the disk image.

<p>This will:</p>
  <ul>
    <li>Put the DOS 3.3 File System on the disk,</li>
    <li>Write DOS 3.3 to the first 3 tracks and make the disk bootable,</li>
    <li>Write your program to disk.</li>
  </ul>
</li>
</ol>

<p>You now have a working disk
image, which you can use to save documents or other information. If you
want to fill this image with data from a real floppy disk that you
have, then you need to "transfer" the disk's data. See the <a href="ddi-transfer.html">Transferring
Disk Images</a> topic for more information. </p>

<p>Please note that not all disk image types supported by
AppleWin can be created in this manner.&nbsp; Since there is no way
to detect the image type from the image itself, it is determined by the
given file extension only. Six extensions are allowed:</p>

<ul>
  <li>.DSK -- DOS 3.3 sector order,</li>
  <li>.DO -- DOS 3.3 sector order,</li>
  <li>.PO -- ProDOS sector order,</li>
  <li>.HDV -- ProDOS (hard drive) volume in ProDOS sector order,</li>
  <li>.NIB -- older raw nibble image that supports up to 6656 (0x1A00) nibbles/tracks, and</li>
  <li>.WOZ -- the newest format that supports all copy protection formats.</li>
</ul>
<p>If the extension is completely omitted, <span style="font-family: Courier New,Courier,monospace;">.DSK</span> will be chosen by default.</p>
